Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to the strong chemical Si–O bonds of silicon dioxide. Imperfections of the glass, such as bubbles, and in particular surface flaws, such as scratches, have a great effect on the strength of glass and decrease it even more than for other brittle materials.

WebbGlass is a non-crystalline, often transparent amorphous solid. Glasses have widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Since glass is an amorphous (non-crystalline) solid, it is usually formed by the solidification of a melt without crystallisation. Webb19 maj 2015 · These applications use traditional oxide glasses; beyond these, bulk metallic glasses have been developed, leading to an expanding array of applications. Metallic glasses are injection moldable, yet have no grain boundaries and therefore are stronger than titanium and can be formed into features 100 times smaller than conventional metals. dailychainWebb31 mars 2024 · Theoretical descriptions of glass structure rely on long-standing principles that define motifs of atoms.
